BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention is related to a method an a machine for the production of glassware articles and more specifically to a method and a machine, as an individual forming section including single or multiple cavities, which can be grouped to constitute a glassware forming machine of the type including multiple individual forming sections, normally including from six to eight individual forming sections, for the production of glass bottles, jars, tumblers and other glassware articles by the blow-and-blow, press-and-blow, press-and-blow paste mold or direct-press processes.

2. Description of the Related Art

Glassware articles such as narrow neck glass bottles are normally produced in glassware forming machines of the type which may include multiple similar forming sections, by the blow-and-blow process, while wide neck glass jars, tumblers and other glassware articles are produced in the so named “E” and “F” Series forming machines by the press-and-blow process, in both, the so named hot molds and paste mold.

Glass bottles known as narrow neck glass containers, can also be produced by the well-known press-and-blow process, in the above mentioned E and F machines.

Nowadays the production velocity or forming cycles of the machines including multiple-sections and E and F machines, have reached to an optimum status and the maximum number of glassware articles has been achieved by providing multiple cavities (usually two to four) in each individual forming section of the machine.

Looking for an increasing in the number of glassware articles per forming cycle on each section of the machine, attempts have been made to introduce additional forming stations in each section, for example an additional article forming apparatus (blow mold, blow head) which could carry out a forming task (receiving a just formed parison from a single parison forming apparatus and beginning the forming blown), while another similar equipment is carrying out a following forming task on the forming cycle (opening the blow mold for transferring a just formed article to a cooling dead plate and being prepared to receive another following parison from the parison forming apparatus).

Representative of such forming machines, are the so named “one-two station machines”, disclosed in U.S. Pat. Nos. 4,094,656; 4,137,061 and 4,162,911 of Mallory, including a single stationary parison forming station and two article finishing stations, one finishing station at each side of the parison forming station in the same line known as the “cold-side” of the machine, eliminating the so named hot-side, and in U.S. Pat. Nos. 4,244,756 and 4,293,327 of Northup, disclosing a single parison forming station placed in the hot-side of the machine, and two article finishing stations, mounted one above the other on a lifting and lowering mechanism, alternatively rising and lowering each forming station for forming the articles.

However, by increasing the number of forming stations, the number of forming molds and surrounding equipment (either for single or multiple cavities) are consequently increased, increasing in turn the operation cost of the machine.

Other attempts to increase the velocity of production and the quality of the glassware articles in the multiple-section machines and E and F machines, has been focused on providing three consecutive forming stations, comprising a first parison forming station, an intermediate station for re-heating and/or stretching of the parison, and a third station for finishing the glassware article.

Representative of these “three station” forming machines are the U.S. Pat. Nos. 3,914,120; 4.009,016; 4,010,021 of Foster; U.S. Pat. No. 4,255,177 of Fenton; U.S. Pat. No. 4,255,178 of Braithwite; U.S. Pat. No. 4,255,179 of Foster; U.S. Pat. No. 4,276,076 of Fenton; U.S. Pat. No. 4,325,725 of Fujimoto and U.S. Pat. No. 4,507,136 of Northup.

The differences between each of these three step forming processes disclosed by the above U.S. patents, can be firstly determined by the parison forming orientation in an upright orientation, as disclosed in U.S. Pat. Nos. 3,914,120; 4,009,016; 4,010,021, all of them of Foster, and U.S. Pat. No. 4,255,178 of Braithwait, and in an inverted orientation, as disclosed in U.S. Pat. No. 4,555,177 of Fenton, U.S. Pat. No. 4,255,179 of Foster, U.S. Pat. No. 4,325,725 of Fujimoto, and U.S. Pat. No. 4,507,136 of Northrup.

Further differences between the above disclosed three step forming processes, are determined by the apparatuses to transfer the parison and finished article through the parison forming step, the intermediate step and the finishing and take out steps.

For example, U.S. Pat. Nos. 3,914,120; 4,009,016; 4,010,021, and 4,255,178 disclose a linear transference of the parison in an upright position from the parison forming station, to the intermediate station, then a linearly transference of the parison from the intermediate station to a blow molding station, and finally, a linearly transference of the finished article, to a cooling dead plate.

Unlikely to the above disclosed glassware forming machines and apparatuses, U.S. Pat. Nos. 2,555,177; 4,255,179; 4,325,725, and 4,507,136, disclose a first transference step including inverting of the parison from an inverted position at the parison forming station, to an upright position at the intermediate station; a second linear transference step from the intermediate station to a final forming (blowing) station; and a third linear transference step from the final forming station to the cooling dead plate. The second and third linear transference steps being carried out by a generally similar transference apparatus.

Other differences between the apparatuses disclosed in the above-referred patents can be found in connection with the very specific apparatuses to carry out the transference of the parison and the final glassware article.

The main objective sought by the introduction of the intermediate station in these glassware forming machines, has been to release the task of a previous mechanism to be in an conditions to repeat a new forming cycle, without having to wait that a following mechanism performs its respective task, to turn back at its original position to begin a new forming cycle.

However, the above objectives have been difficult to be achieved because of the configuration of the mechanisms constituting the machine, which have been the same as the conventional and well-known ones.

Applicants, looking for a win-to-win machine, i.e. seeking to obtain the objectives of increasing the velocity of the machine and a reduction of the forming cycle time, the efficiency of its performance and an increasing in the quality of the articles to be produced, as well as seeking to make standard some mechanisms which perform similar tasks, and equipping them only with their specific instruments to perform their specific function, reducing as much as possible the cost of equipping a machine, the number of mechanisms in storage, and simplicity of mounting the specific instruments on common mechanisms and apparatuses, applicants reached to the following concept of a new glassware forming machine comprising a combination of some new apparatuses, and a new method for the production of hollow glassware articles.

In the first place, applicants visualized that an intermediate station is conveniently necessary so that the re-heating of the glass surface of a just formed parison be continued outside the blank mold in order to immediately release the task of the blank mold, enabling it to carry out another forming cycle, and permitting to carry out a stretching of the parison, all of which also results in an increase in the velocity of production and in a better quality of the article.

Additionally, applicants recognized that the inverting arm including a neck ring mold, of a typical inverting mechanism, had to be in a standing position during a parison forming cycle and to wait for the opening of the blank mold, to initiate the inverting cycle, release the parison at the intermediate station and turn back at the parison forming position, to begin another forming cycle.

To overcome the former disadvantage, applicants introduced a new inventive concept for the inverting apparatus, consisting in providing two diametrically opposed and stepped inverting arms, each holding a transferable and open-able neck ring mold (either single or multiple-cavity), so that a first one of said arms, after a parison has been formed at a first parison forming cycle, can firstly rotate 180° clockwise (moving the parison upwardly constricting it) or counterclockwise (moving the parison downwardly stretching it) to release the parison held by a first transferable and open-able neck ring mold, at the intermediate station, while the second arm with a second transferable and open-able neck ring mold is simultaneously placed under the blank mold to perform a second parison forming cycle, and then the first arm with an empty transferable and open-able neck ring mold which has been turned back to said first arm, rotates additional 180° completing a 360° turn, to be placed under the blank mold for a third parison forming cycle, while the second arm is releasing the parison held by the corresponding transferable and open-able neck ring mold, at the intermediate station. In this way, the blank mold do not have to wait that the first arm release the parison at the intermediate station and turn back, to initiate a new parison forming cycle.

New first and second transferable and open-able neck ring molds (either single or multiple-cavity) are provided to be held and handled with absolute independence by each of the arms of the inverting apparatus, by the longitudinal transference apparatus and by the take out apparatus, have also been provided in order to improve the quality of the final product by handling the parison by the neck ring at a uniform temperature, thus avoiding that the formed parison had to be handled by other components at different temperatures which may cause checks, efforts or deformations in the parison, which result in a poor quality of the finished articles.

The independence and transference ability of these transferable and open-able neck ring molds of the present invention, is possible in the machine of the present invention because of the existence of the unidirectional indexing-rotary inverting apparatus including the first and second stepped and diametrically opposed arms, which are able to hold a transferable and open-able neck ring mold, so that, while a first transferable and open-able neck ring mold is transferred from the first arm at the intermediate station to the blown molding station for forming a finished article, the second arm with a second transferable and open-able neck ring mold is placed at the parison forming station, in a parison forming cycle and once the parison is formed and able to be inverted at the intermediate station, the first arm has received back the first transferable and open-able neck ring mold and rotated other 180° completing a 360° turn, to be placed again at the parison forming station.

Also, although a typical baffle apparatus could be included in the machine, mainly for the blow-and-blow forming process, this apparatus can be configured in accordance with the machine of the present invention, by including a new oscillating apparatus named “rotolinear apparatus”, which may also be useful for operating a glass gob guide channel, the blank mold apparatus, the final blow apparatus and any other apparatus, for firstly rotate, then place an actuating mechanism to their respective active positions, and then retire them to an initial inactive position, which includes a new configuration of cams and cam followers to impart reliable oscillation and lowering and lifting movements, overcoming any backlash which could cause misalignment of the baffle apparatus or any other apparatuses, with the following apparatuses of the forming sequence.

A new equalizing apparatus has also been provided at the baffle apparatus and at the final blow apparatus, for multiple-cavity, for mounting bottom blank mold heads and uniformly place them on the blank molds or the blow molds, effectively adjusting whatever misarrange which may exist both, in the baffle or blow heads, or in the blank mold or blow molds.

In this way, this new glassware forming machine overcomes a number of difficulties of the known glassware forming machines, affording a win in the forming cycle time, which is estimated at a 32.6%, and allows an increase in the production and an improvement in the quality of the hollow glassware articles, as will be specifically disclosed in the following detailed description of the invention.

SUMMARY OF THE INVENTION

It is therefore a main object of the present invention, to provide a new machine for the production of hollow glassware articles, which allows a reduction in the forming cycle time of the machine, and an improvement in the quality of the glassware articles produced.

It is another main object of present invention, to provide a new machine for the production of hollow glassware articles, of the above disclosed nature, which can be easily equipped to operate as a blow-and-blow forming process or a press-and-blow forming process, in its embodiments of two-halve blank molds, solid blank mold, and pasted mold for producing seamless glassware articles.

It is an additional main object of present invention, to provide a new machine for the production of hollow glassware articles, of the above disclosed nature, which includes an intermediate station which, in combination with a new indexed rotary inverting apparatus rotating 180° clockwise or counterclockwise, and new forming and handling apparatuses, allows to increase the velocity of the machine (i.e. a reduction in the forming cycle time) and the improvement on the quality of the produced glassware articles.

It is a further main object of present invention, to provide a new machine for the production of hollow glassware articles, of the above disclosed nature, which includes new apparatuses and mechanisms which are standard for other apparatuses of the forming machine, performing similar tasks, which are just specifically equipped to perform their specific tasks.

It is still a further main object of present invention, to provide a new machine for the production of hollow glassware articles, of the above disclosed nature, in which the transferable and open-able neck ring molds, parison molds and blow molds, are mounted to be placed at a so named blank mold “zero-line” in the machine, which is a unique position standard for any size of parisons and glassware articles to be produced.

A summary of the advantages of the machine for the production of hollow glassware articles, in accordance with the present invention, are as follows.

-   -   It is suitable for the production of hollow glassware articles,         such as bottles, jars, tumblers and other glassware articles, by         the blow-and-blow or press-and-blow, press-and-blow paste mold         and direct press processes in a glassware forming machine         including multiple machine sections and multiple cavities.     -   A single machine section can be quickly interchanged at a         multiple-section machine, by another ready-for-operation one,         without retiring said multiple-section machine from the working         area, for maintenance, repairing and/or actualizing.     -   The transferable and open-able neck ring molds are placed at a         constant “zero-line” height for the different height of articles         to be produced, so that height adjustments are unnecessary.     -   The unidirectional inverting apparatus are placed at a constant         “zero-line” height for the different height of articles to be         produced and/or processes, so that height adjustments are         unnecessary.     -   The pressing plunger apparatus is placed at a constant         “zero-line” height for the different height of articles to be         produced and/or processes, so that height adjustments are         unnecessary.     -   The pressing plunger apparatus is placed at a constant         “zero-line” height for the different height of articles to be         produced, requiring only a rapid change of the pressing plunger         or neck ring plunger, so that height adjustments are         unnecessary.     -   The variable compensator of the pressing plunger apparatus,         allows to change the height of the parison     -   The servo-controlled bi-directional curvilinear transference         apparatus is placed at a constant “zero-line” height for the         different height of articles to be produced, so that height         adjustments are unnecessary.     -   The blow head apparatus is placed at a constant “zero-line”         height, for the different height of articles to be produced, so         that height adjustments are unnecessary.     -   The bidirectional curvilinear translation take out apparatus is         placed at a constant “zero-line” height, for the different         height of articles to be produced, so that height adjustments         are unnecessary.     -   The neck ring holding arms of servo-controlled unidirectional         inverting apparatus, are mounted in a reduced inversion radius         which allows a reduction of inertial forces for the inversion         servo-controlled path of the parison.     -   The oscillating mechanism is the same for guide-funnel         apparatus, the baffle apparatus and the blow head apparatus, but         arranged in a left or right arrangement only for the         guide-funnel apparatus.     -   The opening and closing mechanism, is the same for the blank         mold apparatus and the blow mold apparatus.     -   The driving mechanism is the same for the servo-controlled         unidirectional inverting apparatus, the servo-controlled         bi-directional curvilinear transference apparatus, and the         servo-controlled bi-directional curvilinear take out apparatus,         but arranged in a left or right arrangement only for the         servo-controlled bi-directional curvilinear transference         apparatus.     -   The equalizing mechanism is the same for the baffle apparatus         and the blow head apparatus.     -   The machine is able to change from a blow-and-blow process to a         press-and-blow process or direct press, and vice versa, changing         only the mold tooling, without changing any mechanism, kits or         position adjustments

It is also a main objective of the present invention, to provide a new method for the production of hollow glassware articles, which allows an increasing in the velocity of production and a reduction of the forming cycle time of the machine, and an improvement in the quality of the glassware articles produced.

It is another main objective of the present invention, to provide a new method for the production of hollow glassware articles, in which a first parison, held by a first transferable and open-able neck ring mold mounted on a first arm of an inverting apparatus, is inverted, by an indexed rotation at 180°, clockwise or counterclockwise, from an inverted orientation to an upright orientation at an intermediate station, while a second transferable and open-able neck ring mold mounted on a second arm of the inverting apparatus is simultaneously placed at the parison forming station, to carry out a parison forming cycle.

It is jet another main objective of the present invention, to provide a new method for the production of hollow glassware articles, in which the first formed parison held by the first transferable and open-able neck ring mold is transferred, through a semicircular path, from the intermediate station, to a blow molding station, in which the first parison is released into a blow mold, turning back the first transferable and open-able neck ring mold empty to the first arm of the inverting apparatus, at the intermediate station to be placed again at the parison forming station, by rotating the first arm additional 180°, completing a 360° turn, while the second arm reaches to the intermediate station to carry out a transferring cycle.

for a press-and-blow process, in an inactive position, this parison forming apparatus, is in a retracted position maintaining the pressing plunger 209 in a position allowing an inverting path of the unidirectional rotary inverting apparatus UIA and, by the effect of the operating fluid fed to the lower chamber 167 under the first piston 166, simultaneously releasing the fluid from the upper chamber 168 of the first piston rod 170, from the upper chamber 184′ of the second piston rod 188, and from the chamber 202 of the third pressing piston 201, and therefore the first internal spring 213 is extended, pulling the variable adapting segment 222, and the spring SP is also expanded, in order to place the pressing plunger 209 at a charging position;

then, once the glass gob has been fed into the blank mold BM and the baffle apparatus BA is placed at the top of the blank mold BM, operating fluid is fed to the lower chamber 173′ under the second piston 184, placing it at a fully extended position and automatically connecting the passage 182 of the second end cap rod bushing 181 with the perforations 189 of the hollow piston rod 188 and of internal concentric grooved tube 190 for feeding operating fluid to the third final pressing piston 201, when decided, so that the pressing plunger 209 is placed at its parison forming position; and finally, once the parison P has been finished, the first, second and third pistons 165, 184 and 201 are simultaneously retracted to its initial position for a new parison forming cycle;

for a blow-and-blow process, the pressing plunger 209 is a short neck ring forming plunger 209′ (FIGS. 6J to 6L), including a central passage 165′ connecting with the central conduit 165, and a plurality of diagonal passages DP at about 45° regarding the central passage 165′, leading to a side of the short neck ring forming plunger 209′, so that once the first and second pistons 166, 184 are placed at a fully extended position, the short neck ring forming plunger 209′ is placed at a charging and forming position, in sealed abutment against the transferable and open-able neck ring mold 1, due to the fluid pressure at the chamber 202 and third pressing piston 201, and introducing the short neck ring forming plunger 209′ into the cavity of the transferable and open-able neck ring mold 1 for receiving a molten glass gob, and then by feeding operating fluid to the chamber 202, will cause that the flange piston FP of the short pressing plunger 209′ will be in sealing contact with the neck ring mold halves 3,3′ or the one-piece annular guide 5 in order to allow a vacuum be applied through the diagonal passages DP and through the passage 165 and 165′ to fill the transferable and open-able neck ring mold 1 with the glass gob; and then the operating fluid is released from the lower chamber 202 under the third pressing piston 201, extending the spring SP and the short neck ring forming plunger 209′ is retracted, allowing a counter-blow fluid passing through the diagonal passages DP, for finishing the parison P; and finally, once the parison P has been finished, the first, second and third pistons 166, 184 and 201 are simultaneously retracted to its initial position for a new parison forming cycle.

By using a three-positions directional valve (not illustrated), said central passage 165′ may provide both a positive or negative pressure, so that, for a blow-and-blow process, the short neck ring forming plunger 209′ at a charging position, may firstly provide a vacuum through the central passage 165′ and diagonal passages DP, in order that the glass gob completely and rapidly fills the transferable and open-able neck ring mold 1, in addition to the settle blow provided by the baffle head 103 of the baffle apparatus BA, and then, when the piston 201 is retracted, the three-positions directional valve changes to positive pressure providing a counter-blow to form the parison P, and in a third position, said three-positions directional valve is under neutral inactive position.

For a convenience, an horizontal elongated nozzle NZ (shown at FIG. 6A), mounted on the top support 161′ of the first cylinder 160, provides a horizontal compressed air curtain in order to avoid that contaminant dust particles, glass chips or grease fall down to the pressing plunger 209 or short neck ring forming plunger 209′.
